What is a closed loop hydronic heating system?
A closed-loop system uses a continuous loop of PEX tubing as a heat exchanger. The tubing is connected to the heat pump and with the proper antifreeze solution, it is circulated throughout. When properly installed, a closed loop system is economical and reliable.
What are the components of a hydronic floor heating system?
Key Components of a Hydronic Radiant Floor Heating System A hydronic system is fairly simple, consisting of a heat source, tubing, plumbing manifold, and liquid medium, heat exchanger, and pump.
What’s the difference between infloor heating and hydronic heating?
Both infloor heating and hot water radiators are sometimes called “hydronic heating” systems and both these options make people feel warmer at lower room temperatures than force air systems. These are some of the reasons hydronics are gaining in popularity.
How does a closed radiant floor heating system work?
Closed Radiant heating system equipped with an automatic fill valve. This low pressure valve will maintain a constant minimum pressure once the system is filled & purged. The photo above is our “Radiant Ready A/T” single zone Closed System for use with an on-demand water heater.
What are the advantages of a closed floor heating system?
The main advantage to this system lies in the fact that, being closed, anti-freeze instead of water can be used as the heat transfer medium. The percentage of anti-freeze (Propylene Glycol) is determined by the type of heat source (on-demand heater or tank-type) and by the guidelines listed on the anti-freeze container.
How does a floor heating and hot water system work?
heater, to provide both floor heating and domestic hot water. The two systems are basically tied together. The same water that ends up in your hot shower or dishwasher, for example, has passed through the floor first. This is a very efficient system because one heat source is doing all the work.

Where does tempered water go in a radiant floor heating system?
The much cooler radiant floor zones receive tempered water from the “mix” port of the mixing valve. The schematic below illustrates this approach. The hotter baseboard radiator returns enter the manifold AFTER the “cold” supply pipe to the mixing valve. In this way, the cooler radiant floor returns can provide ideal tempering water.
